Apple officially states that the Apple Watch is water resistant
with a rating of IPX7, which means the watch can be submerged at
depths up to 1 meter for up to 30 minutes. Apple CEO Tim Cook,
for example, has said in the past that he showers with his Apple
Watch on, but the FoneFox team wanted to see if the device could
survive for even longer, and at greater depths.

FoneFox began their test by seeing how the Apple Watch handled a
typical shower spray.

With a total of 15 minutes submerged and no observed loss of
functionality, the Fone Fox team concluded that the Apple Watch
appears to justify its IPX7 water-resistant rating. While Apple
might not recommend you take the device swimming, you'll likely
find it can survive normal use underwater at conservative depths.
